Major Hip and Knee Joint Replacement in Mississippi
76 Mississippi hospitals report Medicare totals for this DRG, averaging $18,724 (below the $24,455 national mean), with a 4× spread from $7,200 to $31,513. 2 carry an A grade, 0 carry an F.
The Orthopedic procedure Major Hip and Knee Joint Replacement carries DRG code 470 in the CMS classification system. 3,348 hospitals in Mississippi report payment data, averaging $24,455 per procedure — median $23,685, ranging from $7,200 to $58,650. A $58,650 maximum and $7,200 minimum on the same DRG procedure is normal for the Medicare payment system — DRG codes bundle cases that may differ in complexity, and hospital wage-index adjustments alone can move payments by 30% across regions.
Within Mississippi, the 3,348 hospitals reporting this procedure span the full range of ownership types and hospital sizes. The state-specific average ($24,455) is shaped by which hospitals in the state see enough volume to report the DRG code at all. For patients with elective scheduling on Major Hip and Knee Joint Replacement, the cost-comparison logic is straightforward: the per-procedure payment range is meaningfully wide, so the hospital chosen affects total cost. For patients in an emergency, the choice is functionally fixed — but the listed prices still matter for insurance-coverage and out-of-pocket planning.
About This Procedure
Musculoskeletal DRGs include hip and knee replacement, spine fusion, fracture repair, and major joint revision. Implant cost, length of stay, and rehab intensity drive most of the price variation across hospitals — DRGs 469/470 (joint replacement) are among the most-watched price benchmarks in Medicare.
Major Hip and Knee Joint Replacement is Medicare DRG 470 in the Orthopedic category. National Medicare average for this DRG is $24,455 across 3,348 reporting hospitals. The state-level view here filters that universe down to Mississippi only.
Cost Picture in Mississippi
Mississippi's average for this DRG sits below the national Medicare mean. State-level differences are explained primarily by the regional Medicare wage index — the multiplier CMS applies to standardize DRG payments to local labor costs — alongside hospital case mix and the concentration of academic referral centers in the state's larger metros.
Within the state, the 4× spread between the lowest- and highest-reporting facility usually reflects length-of-stay differences, complication adjustments for sicker patients, teaching-status add-ons, and outlier payments for unusually long stays. Two hospitals reporting the same DRG can post meaningfully different totals without anything “wrong” happening at either site. For non-Medicare patients, the more relevant figure is the negotiated commercial rate published in each hospital's machine-readable file under the CMS Hospital Price Transparency Rule.
Quality Alongside Price
For a planned admission, the most useful complement to the cost view is the hospital-specific quality data on CMS Care Compare. The site publishes risk-adjusted measures of mortality, readmission, complication, infection, and patient experience for every Medicare-participating hospital. The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators feed many of these CMS measures.
For complex procedures, hospital-level case volume correlates with outcomes in published research, even after risk adjustment. CMS publishes case counts on Care Compare alongside outcome measures.

Frequently Asked Questions
How much does major hip and knee joint replacement cost in Mississippi?
Major Hip and Knee Joint Replacement (DRG 470) averages $18,724 in total Medicare payment across 76 Mississippi hospitals reporting this code. Within the state, payments span $7,200 to $31,513 — about 4× from cheapest to most expensive.
Is Major Hip and Knee Joint Replacement more or less expensive in Mississippi than nationally?
Mississippi's state-level average of $18,724 sits below the national Medicare average of $24,455 for this DRG. State differences are driven primarily by the regional Medicare wage index, case mix, and the share of high-acuity referral hospitals.
Why is the spread between hospitals so wide?
Variation within a state runs 4× because the same DRG can come with different lengths of stay, complication adjustments, teaching-status add-ons, and outlier payments. The CMS Hospital Price Transparency Rule publishes machine-readable rate files that allow direct comparisons against negotiated commercial rates, which often differ from Medicare totals.
Are these the prices a privately insured patient would pay?
No. Figures here are Medicare DRG payments. Privately insured patients are billed under their plan's negotiated network rate, published in each hospital's price-transparency file. Uninsured patients should ask the hospital for the cash-pay rate, also disclosed under federal price-transparency rules.
Should I choose a hospital based only on price?
No. HospitalCostData is informational. Surgeon experience, hospital volume for the procedure, complication rates, and your specific clinical situation matter at least as much as price. Always discuss options with your physician and review CMS Care Compare quality data alongside any pricing benchmark.
